Don't know what are these marks I haven't give the plant any nuts yet since they are in FoxFarm Ocean forest, and was going to start with big grow(6-4-4) from next watering. Any help will appreciated
Those are nutrient burns. i wouldn't pay it any mind if it's just the ffof doing it they will just grow into it.
Some people say you should feed after two weeks in ffof some say 6. me i feed after one or two and it's usually fine. at 1/2 doses from the feeding chart.
This is auto blue treacle.. It's 25 days from seed, watered it 4 times so far.. Three of them were fully watering. I have two other plants auto as well difference strains but they look fine
Looks like a nutrient burn too me, or light is getting too hot, but I say nutrient burn. Maybe back off a bit on your nutes
Your plants still look great. A little burn on the tips isn't going to hurt them, but if you see it getting worse, then you might worry a little. I use a watering can to feed my plants and occasionally I will get a drop on a leaf here and there, and sure enough, next day that leaf is fried in that spot where the drop was, but the plants are still growing super awesome.
I thought it was a nuts deficiency since I haven't add any nuts yet. I was planning to add some in the next watering. What do you think?
They don't look deficient to me. Just my opinion. I feed my plants regularly, but I have an outdoor setup. I've never grown indoor, but I have many buddies who do.
